Eumorpha labruscae, the gaudy sphinx, is a Neotropical hawkmoth with a relatively large geographical distribution.

It has a combination of green, blue, red and yellow colouration on the wings which gives it an exotic and impressive appearance and also explains its flamboyant common name.

The moth’s Latin name is composed of the Greek word Eumorpha which means well-formed, and labruscae the Latin word for fox grape (Vitis labruscae) - one of the plants on which the larva feeds.
